Predicted to enable fibroblast growth factor binding activity. Acts upstream of or within several processes, including negative regulation of protein processing; negative regulation of transforming growth factor beta receptor signaling pathway; and regulation of chondrocyte differentiation. Located in Golgi membrane and extracellular matrix. Is expressed in several structures, including cartilage condensation; central nervous system; genitourinary system; hemolymphoid system gland; and retina. Orthologous to human GLG1 (golgi glycoprotein 1). [provided by Alliance of Genome Resources, Apr 2022]
